Aryl methyl ketones can be easily converted to 1‐aryl‐2‐dimethylaminomethylpropenones that are known as interesting lead structures for drug development. By reaction of these enone Mannichbases with benzamidines, a series of new 2‐aryl‐5‐aroyl‐3,4,5,6‐tetrahydopyrimidines were synthesized. These structures were characterized according to their lipophilicity. Thirty five tetrahydropyrimidines were

The condensation of 1-aryl-2-dimethylaminomethylprop-2-en-1-ones 4 with 2-aminopyridines 5 gives rise to the 3-benzoyl-3,4-dihydro-2H-pyrido[1,2-a]pyrimidines 3. The reaction is initiated by addition of the pyridine amino group to the enone double bond, followed by deamination and ring closure to give the anellated pyrimidine ring system, which is an excellent precursor for the synthesis of pharmacological active compounds.
